“Love & Hip Hop: Atlanta” star Erica Pinkett was savagely attacked in a nightclub … and Pinkett says she told police the hit was ordered by a jealous rival on the show.

Law enforcement sources tell us … Pinkett was coming out of a bathroom in Atlanta’s Taboo Club June 9 when a woman came up from behind her, hit her in the face and then threw her to the ground and slashed her arm with a razor blade … causing a bloody gash.

Pinkett tells police … she thinks the attack was ordered by fellow “L&HH:A” star Bambi Johnson … because the two have had arguments over Pinkett’s relationship with Johnson’s boyfriend, Lil Scrappy. One of the fights (see video below) aired on the show.

According to the police report – obtained by TMZ — the beating suspect left the club before cops arrived … Stephanie Nicole Harp was arrested this morning for committing aggravated assault with a deadly weapon.

This is kinda old, but we can see why TMZ would report it now being that Stephanie was just arrested today. We did a little digging immediately after the fight and a source at the nightclub told us Pinkett’s wound was caused by broken glass — not a razor blade, after she fell during a tussle. We were also told that the fight wasn’t as bad as people were saying.

We even reached out to Erica’s rep, and when we asked what happened his response was “some bs every is a 100.”

As for Bambi ordering a hit, she responded within days of the fight, denying any role in the incident. Hit the flip for her exact words!
